Rigid PVC is one of the most widely used plastic materials. PVC material is a non-crystalline materials. PVC material in actual use, often by adding stabilizers, lubricants, auxiliary processing agents, pigments, impact agents and other additives. PVC material is not easily flammable, high strength, resistance to climate variability and excellent geometric stability. PVC oxidant, reductant and acid has a very strong resistance. However, it can be concentrated oxidizing acids such as sulfuric acid, concentrated nitric acid corrosion and does not apply to contact with aromatic hydrocarbons, chlorinated hydrocarbons occasions.

PVC melt temperature during processing is a very important process parameters pvc plastic pipe, if this argument would lead to inappropriate material decomposition problem. Very poor flow characteristics of PVC pvc plastic pipe manufacturers, the process is very narrow range. Especially high molecular weight PVC material more difficult to process (this material is usually added to improve the flow characteristics of lubricant), it is often used are low molecular weight PVC material. PVC contraction rate is very low, typically 0.2 to 0.6%. Shandong pvc plastic pipe, pvc plastic pipe, sea Widex Widex provided by Qingdao Rubber Material Co., Ltd.
